Answer:
96
Step-by-step explanation:
To determine how much additional wax was needed to make the taller candle, we determine the volume of each of the candles and find the difference in their volumes
<u>First Candle</u>
- Height=12cm
- Length=4 cm
- Width= 6 cm
Volume=Height X Length X Width
=12 X 4 X 6
=288
<u>Second Candle</u>
The second candle is 4cm higher
- Height=12+4=16cm
- Length=4 cm
- Width= 6 cm
Volume=Height X Length X Width
=16 X 4 X 6
=384
Difference in Volume = 384-288 =96
Therefore, 96
of additional wax was used to make the second candle.

Answer:
2.5 hours
Step-by-step explanation:
The ratio - 300: 5 is the same as 60:1
150:x should equal 60:1
You divide 150 by 60 to get your answer
Answer:
N = -2 1/6
Step-by-step explanation:
1. n/5 = -0.3
5* 5*
n = -1.5
2. -2n= 4 1/3
-2n = 13/3
-2n/ -3 = (13/3)/-2
n = -13/6
n = -2 1/6
Answer:
6.444.... or 6&4/9
Step-by-step explanation:
3(x-5)+2(3x+1)=45<------distributive property
3x-15+6x+2=45 <------combine like terms
9x-13=45 <------addition property of equality
9x=58 <------division property of equality
x=6.444...
